    Abstract:
    BACKGROUND: Exercise training is a well-established intervention for patients with heart failure with reduced and preserved ejection fraction. Still, the evidence of its effects on mortality, hospitalization, and quality of life needs to be more conclusive. We aim to evaluate exercise training clinical outcomes in patients with heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF). METHODS: We searched five databases and three clinical trial registries for RCTs that compared exercise training plus usual care versus usual care alone in congestive heart failure (CHF) patients. We extracted data on all-cause mortality, hospital admission, heart failure hospitalization, and health-related quality of life measured by the Minnesota Living with HF questionnaire (MLHFW) and other scales. We pooled the data using random-effects or fixed-effects models, depending on the heterogeneity of the outcomes. We performed subgroup analyses for patients with heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF). RESULTS: We included 61 RCTs with 9062 participants. There was no mortality benefit, but exercise training improved health-related quality of life, reduced hospital admission at 12 months and longer follow-up, and reduced heart failure hospitalization. We observed substantial enhancement in health-related quality of life and a greater decrease in hospital admissions in the HFpEF group compared to the HFrEF group. CONCLUSIONS: Despite the lack of mortality benefit, exercise training is a beneficial intervention for CHF patients, improving health-related quality of life and reducing hospitalization.
